Intern, Lung Aging (PhD Only)

Calico•South San Francisco, CA

23d•$45 - $70•Onsite

About The Position

Who We Are: Calico (Calico Life Sciences LLC) is an Alphabet-founded research and development company whose mission is to harness advanced technologies and model systems to increase our understanding of the biology that controls human aging. Calico will use that knowledge to devise interventions that enable people to lead longer and healthier lives. Calico’s highly innovative technology labs, its commitment to curiosity-driven discovery science, and, with academic and industry partners, its vibrant drug-development pipeline, together create an inspiring and exciting place to catalyze and enable medical breakthroughs. Position description: Calico is seeking an intern to join the Gillich lab. To succeed, you will need to be an enthusiastic team player, detail-oriented, extremely organized and comfortable working on complex problems. In this position you will use CRISPR screening and cutting-edge functional genomics approaches to discover lung aging targets. The successful candidate will work closely with members of the Gillich and Cellular Phenotyping labs to establish a platform for co-culturing alveolar organoids derived from primary alveolar type 2 (AT2) cells with alveolar fibroblasts. Using this system, you will screen for reversal of lung aging phenotypes in the co-cultures using phenotypic and transcriptomic readouts. This project will contribute to our goal of understanding mechanisms of aging and identifying interventions that prevent or reverse aging and disease pathologies in the lung. About our Program: Calico’s internship program is a paid 12-week program over the summer for students interested in understanding the fundamental science of aging and finding treatments for the associated and intractable diseases. Working in a collaborative environment and fully embedded in one of our labs/teams, Calico interns tackle a unique project under the mentorship of at least one of our scientists or engineers . Program Features: 3-month summer timeline In-person experience at our offices in South San Francisco Matching with at least one Calico mentor Group supplemental activities weekly featuring guest speakers, Senior Leadership spotlights, and discussion groups on aging science, our drug development approach, and more End-of-summer company-wide project showcase and poster session Competitive compensation ($45 - $70/hour) and monthly living expenses stipend Program Eligibility: Able to work in-person at our offices in South San Francisco Free for a consecutive period of 11-12 weeks in June, July, and August Not graduating before December 2026 Exception for students enrolling into a graduate degree program in Fall 2026 Must be enrolled in a US university Must apply by application deadline: February 1, 2026.
